HVAC And Building Services
Building plant runs a lot of pneumatic actuation, and HVAC systems appear on the application lists of both the Type 1000 and the Type 1500. The instrument that matters here is usually the compact one, because plant room space was allocated before the controls were specified.

What Makes This Application Difficult
Plant rooms have no space left
A full-size transducer on every loop is not going to fit in the panel that exists.
Several loops in one cabinet
Individually mounted instruments turn into a maintenance problem and an air piping problem at the same time.
Low air consumption matters at scale
Dozens of units on one header add up, and a compressor sized for the building does not grow.
Terminations vary by contractor
Conduit on one job, DIN plugs on the next, terminal blocks on the one after.
How The Range Addresses It
The T1500 is the compact instrument: a small footprint, ports on the front and the back, and DIN rail and manifold kits giving three, five or ten mounting points. Air consumption on the standard range build is 3 SCFH at 15 psi output. Electrical connections are catalogued as conduit 1/2 NPT or BSPT, terminal block, or Hirschmann DIN 43 650-A connectors, so one model covers whichever standard the job uses.

Questions From HVAC And Building Services Buyers
What is the smallest transducer you supply
The 550 series is the miniature body, and the T1500 is the compact force balance instrument with manifold mounting.
Can several transducers share one mounting
Yes. The T1500 has DIN rail and manifold kits with three, five or ten mounting points, and the T6000 supports 3, 5, 10 and 15 unit manifold configurations.
How much air does a compact unit consume
The T1500 standard range build consumes a maximum of 3 SCFH at 15 psi (1.0 BAR) output.
